Configuration

training_design

Define the training design, i.e. the target Y to use for the model.

Type : ListMaximum occurrences number : -1

target_name

The name of the 'columns' or 'row_tag keys' to use as targets or labels.

Type : string

target_origin

Optional

The origin of the target. Notice: Targets comming from a 'row_tag' are always considered as categorical.

Type : stringDefault value : column

target_type

Optional

The type of the target (categorical or numerical). Set 'auto' to infer the correct type. Notice: targets comming from row_tags are allways considered as categorical

Type : stringDefault value : auto

nb_neighbors

Optional

Type : intDefault value : 5
